DEVICE FOR DISCHARGING ASHES AND CINDERS FROM COAL-STOVES.

SPEGIFICATIQQPforming part of Letters Patent No. 422,904, dated March11, 1890.

Application filed December 5, 1887. Serial No. 256,976- (No model.)

To aZZ whom it 11mg concern.-' I

Be-i't known that I, CURTIS T. BENEDICT, of Milwaukee, in the county ofMilwaukee and State of Wisconsin, have invented new and useful Devicesfor Discharging Ashes and Cinders from Coal-Stoves; and I do herebydeclare the following to be a full, clear, and exact description of saidinvention, reference being had to the accompanying drawings, and to theletters of reference marked thereon, which form a part of thisspecification.

This newly-invented device is intended and adapted especially for usewith that class of coal-stoves having an interior fire=pot at or nearthe base of the stove, particularly heating stoves such as are commonlyknown as base-heaters, and also direct-draft stoves.

In the drawings, Figure l is a central vertical section of the lowerpart of a base-heating coal-stove with my newly-invented device inconnection therewith. Fig. 2 .is a modified form of my device adapted tobe used in connection with a stove on the first floor, and also withanother stove on the second floor. Figs. 3 and at are each a form ofdamper or gate used in my device. Fig. 5 is a top view of the cover ofthe ash-receptacle and of the sifter in connection therewith.

The same letters refer to like parts in all the views.

In the drawings, A represents the first or grade floor of a building,and 13 represents the second or chamber floor of the same building. TheshellG of the stove supports afirepot D, at the bottom of which is thehorizontal grateE, andbeneath and behind the fire pot is a duct orpassage F for the smoke and gases leading up into the smoke pipe G.These features are such as pertain to the stoves now incommon use. Belowthe firepot and grate I provide an upwardly-opening funnel shaped ashreceiver H. The upper end of this ash-receiver is as wide as or widerthan the bottom of the fire-pot, and is preferably as large as and ismade to fit closely Within the shell 0, making a tight joint therewith,so that no ashes can pass out between the shell and the top of thereceiver H, and that all the ashes and cinders as they escape from thefire-pot through the grate E fall into the ash receiver IL Forconvenience of support of the receiver H. it may be provided with ashoulder I, adapted to rest on the bottomJ of the stove. The receiver Hat its lower end passes downwardly centrally through the bottom J of thestove and opens downwardly into the descending ash flue convenientlyformed by a pipe K. This pipe K is fitted to and makes a tight jointwith the lower end of the ash-receiver H and passes downwardly throughthe floor A to the ash-receptacle L. In this flue, and preferably belowthe floor A, are two dampers or gates M, made as nearly airtight asconsistent with ordinary workmanship, which dampers are located at adistance apart, and are intended and adapted to prevent a draft of airupwardly into the stove, as both of them are not open at the same time,and also to check and control the downward passage of the ashes andcinders. As a convenient form of such damper a hinged gate openingdownwardly, provided with a counterpoise N, is best adapted for thepurpose.

As it is sometimes desirable to separate the ashes from thepartly-burned coal, I provide a sifting chamber P at the lower end oftheflue, eitherforming a part of or secured to the pipe K, provided withflanges or ways R, on which a sitter S is supported and maybereciprocated, the sifter S being provided with a handle S, for thepurpose of its manipulation.

An ash-receptacle L is provided, which may be a permanent ash pit, suchas is shown in Fig. 2, or, preferably, a removable box such as is shownin Fig. 1, and when it is a removable box it is provided with anupwardly projecting top or collar T, provided with a swinging door U,adapted to close one side of the collar, which side of the collar isotherwise open to permit the passage of the walls of the chamber Ptherethrough laterally, the collar T being of such size as to admit andfit neatly to the walls of chamber P. By this construction asufficiently close connection between the chamber P and receptacle L ismade to avoid the escape of ashes therethrough in ordinary use, Whilewhen the door U is open the receptacle L may be readily removedlaterally frombeneath the chamber P, for removing the ashes therefrom.

On the floor beneath the stove is a zinc V, provided with an aperture,through which the pipe K passes, about which pipe 011 the zinc maybeplaced a collarV', if desired, formal:- ing a tighter joint.

When the stove from which ashes are to be discharged is located in thesecond story of the building, the ash-flue maybe extended up through thefirst story into the second story, as shown in Fig. 2, and if at thesame time there-is a stove in the first story from which it is desiredto discharge the ashes into the common flue a branch pipe K may beconstructed. from the bottomv of the ash-receiver H to the principalflue for that purpose.

The ashes may be separated from the half burned coal and cinders to someextent by constructing the lower. end of; the pipe K within-the pit L ona lateraland downward angle, and-constructing. the bottom part of,

this. inclined. portionof the flue inv the-form of a sieve W,orotherwise makingapertures for.

the ashes .to fall through while the cinders and half.- burned. coal arecarried out and; dis

chargedsthrough its open end.

Itwill'beunderstood that in using this device theashes. and cinders, as.they. are dis-.

chargedfrom the fire-potthrongh. the grate,

will-falLupon the upper damper M, and-when desired, the upper damper.being .opened, the

asheswilLfall through upon the lower damper M, andwhentlie lower damper.M. is opened the asheswill'fall upon thesieve, so that-by usingtwodampers, onlyone oft-which is open at. the same time, the possibility ofanynp; ward; current-of. air intothe stove willv be obviated.

What I claim as new, and desire .to secure by Letters Patent, is-

1. Anash-discharging device consisting of a funnel shaped.receiver.located. in the. bot tomofastove, and a duststight. pipe .or, flueleading. from. the receiverndownwardly into a. room below that inwhichthe stove is. 10-. cated, in combination with, two automatic 3 damperslocated in the flue ata distance apart, the dampers beinghinged toop enseverally downwardly, being each'provided with a counterpoise, wherebyit is adapted to close automatically but yieldingly under considerableweight, substantially as described.

' 2. In an ash-discharging device, the combination, with a pipe or flueleading directly from the base of a. stove into a room below, of asifting-chamber located at the lower end of the flue in the room belowthe stove, a reciprocating sieve. therein, and. a removableIash-receptacle thereunder, substantially as ;a main pipe..leadingdirectly-from the base ot a stovefin, the secondstoryof; a building @toa roombelow. the first; story, and a, branch.
